HOLLAND FURNACE COMPANY, OF HOLLAND, MICHIGAN, A CORPORATION OF MICHIGAN.

PORTABLE coNvnYEn.

To all whom it may concern:

Be it known that we, OSCAR P. NYSTROM and MARTIN DE LIN, citizens of the United Statesof America, residing at Holland, in the county of Ottawa and State of Michi- "ga'n, have invented certain new-and useful I Improvements in Portable Conveyers; and

we do hereby declare the following to be a full, clear,and exact description of the inventiomsuch as will enable others skilled in theart to which it appertains to make'and use the same.

This invention relates to a portable conveyer which is adapted to be of use in excavating cellars and the like, particularly under buildings such as houses. A Many times in the installation of afurnace in a house, no basement or cellar has ever been dug thereunder such as is necessary to receive the furnace, and the digging thereof after the house isbuilt is .a very hard and costly proceeding.- The present invention is designed to be used, one end thereof being capable of insertion under the building while the other end may be extended to a distance beyond the outline of the building. and the dirt-shoveled on to the inner end of the conveyer is'carried upwardly and outwardly to a point away from the house'or other building under. which the excavation is made. Our invention has for its primary object and purpose the production of a conveyer-of this character which is run by a gasoline engine or similar motor. which can 1 be adjusted to different angles to the vertical and which may be readilymovedfrom one place to another.- Subsidiary to this primary object are many other-objects and purposes directed to the production of the machine in a simple and economical manner and one which is particularlv effective for the purposes for which it is designed.

The invention by means of which these objects and purposes are attained as well as many others not at this time specifically stated, together with many novel constructions and-arrangements of parts for effecting the same, is illustrated in the accompanying drawings, in .which.

Fig. 1 is a side elevation of the conveyer showing the same positioned at an angleto the horizontal.

Fig.2 is a like view, the conveytr being 'positioned substantially horizontal, the position it occupies when it is to-be moved.

Fig- 3 is a side elevation showing the same as used in excavation, and with the construction slightly modified to change the conveyor into an endless conveyor and digger.

Fig. 4 is an enlarged side elevation of the machine with parts broken away and shown in section to better illustrate the construction.

Fig. 5 is a vertical section taken on the plane of line 55 of Fig. 4, looking as indicated by the arrows.

Fig. 6 is a fragmentary side elevation of the machine at the side opposite that shown in Fig. 'showing the engine and driving connections between. it and the conveyor proper.

Fig. 7 is a transverse vertic'al section on the plane of line 7-7, of Fig. 4.

' Fig. '8 is a fragmentary enlarged vertical section taken longitudinally of the machine at itsmid-portion and. showing the conveyor construction in detail, and

Fig. 9 is a fragmentary transverse vertical section on the plane. of line 9, 9, of

parts in the different figures of the drawings.

In the construction of the machine, an axle-1 is used at the ends of which wheels 2 are mounted. Suspended from' the axle near one of the wheels are a pair of spaced apart straps 3, the lower ends of which connect to the front ends of two horizontal bars 4 at'the opposite ends of which downwardly extending legs 5 are connected adapted to rest at their lower ends on the ground or other support on which the wheels 2 bear. An engine, preferably, a small gasoline motor 6 is carried on and above the bars 4. A rod 7 is connected loosely at its lower end to an angle bar 8 in turn permanently secured to and between the upper ends of the legs 5, said rod at its free end being formed with a hook 7 for a purpose which will be later described;

Two spaced apart vertical bars 9 are con-- -nected at their lower ends to members 10 secured and equipped with bearings through which a shaft 13 passes. Referring to Fig. 9,

it will be seen that the shaft passes through a bearing sleeve 14 which is extended inwardly from the member 12 to pass through an enlarged boss 15 adjacent the upper end of a member 16 which at its lower portion is formed into a gear segment having a series of gear teeth 17 cut in its curved under side. The teeth 17 mesh with pinions -18 keyed on a cross shaft which at its ends has rotatable mounting in openings in the bars 9. The shaft is shown at 19 in Figs. 5, 8 and 9.

Each of the members 16 is formed with an inwardly extending ledge 16 at the upper side of the gear segment which serves as a support for an angle iron bar 20 wh1ch is permanently secured thereto. Vertical side plates 21 extend upwardly along the inner sides of the members 16 above the ledges and between the said members 16 and and the vertical legs of the bars '20, being permanently secured thereto and at the upper edges of said plates other angle bars 22 are permanently secured, lying directly above the bars 20. Atthe outer side and at each vertical edge of each plate 21, vertical angles 23 are fastened, and a lattice work of vertical and diagonal bars, indicated at 24 is interposed between the upper and lower bars 20 and 22 at each side of the structure for a distance beyond each edge of plates 23. At one end of the beam or girder thus made, side plates 25 are permanently fastened and at the other similar side plates 26 are secured as shown. At the ends ofthe beam, vertical angles 27 are used to connect the upper and lower bars 20 and 22, and at one end, as shown in Fig. 4, an inclined short bar 28 is used. A lower cross plate 29 (see Fig. 7) connects the lower bars 20 at the ends of the beam, and at one end, the left as shown in Fig. 4, an upper cross plate 30 connects the upper bars, said plate 30 having upwardly pressed parallel longitudinal ribs 31 made therein,

'the purpose of which will be hereafter described. At intermediate points where the plate 30 is not over the upper bars 22, a plate 32 is used over the upper horizontal leg of each bar 22. as shown in Fig. 9.

On one end of the shaft 19 a worm wheel 33 is secured (see Fig. 4) with which a worm 34 engages, the same being at the lower end of a vertical shaft or rod 35 which is equipped with a hand wheel 36 at its upper end. The worm and worm wheel are enclosed in a suitable casing 37. Manual operation of the hand wheel serves to turn shaft 19 with pinions 18 thereon, whereby the construction supported between the bars 9 may be turned to different angles with respect thereto. The turning movement of said construction is about the axis of the horizontal shaft 13.

42. When the engine is running, the shaft 13 is driven continuously, as is evident.

The shaft 13 adjacent each side carries a chain wheel 44. Above an to one side of the shaft 13, another shaft 45'is positioned havin chain wheels 46 thereon in the same vertical planes with the wheels 44. The ends of shaft 45 pass through the side plates .21 and are carried in suitable bearings 47 attached to the outer sides of late 21 the plates 21. 'At one end of the beam or girder. carried between the bars 9, a shaft 48 is mounted horizontally between and supported at its ends by the plates 25, it also having chain carrying wheels 49 thereon.

At the opposite end of the beam or girder,

still another shaft 50 is mounted horizontally betweenthe plates 26, beink 'carried at their ends in blocks 51 which are slidably mounted in suitable guides 52, being adjusted by means of the adjusting screws 53.

This shaft also has chain carrying wheels thereon. And finally a short distance in front and above the shaft 50, still another shaft 54 is suitably mounted on bearings depending from'the upper bars 22, it having wheels 55 thereon.

Two endless chains 56 pass around the various chain carrying wheels 44, 46, 49, 55

and those not shown on they shaft 50. The

chains pass above the wheels 44, 46 and 55, the lower run of the chain passing over the wheels 44 and the upper run of the chain over the wheels 46 and 55. The wheels 44 on shaft 13 are the driving wheels for moving the chains in unison, and the tension of said chains is adjusted by the adjusting screws 53. I

The links of the chains at spaced intervals have inwardly projecting lugs 57 to which cross plates 58 of metal are riveted, saidplates having upwardly extending ends 59,

as shown-whereby on the straight upper run of the chain a moving trough is made into which dirt or other material may be placed and carried to the delivery end of the machine and there dumped as the chains pass around the shaft 50. The endsof the sides 59 may pass by each other to a limited extent when necessary, as in passing over the wheels 44, as shown in Fig. 8. The ends of the bottoms 58 are formed at one end with an upturned lip 60 and at the other with an upwardly curved-overhangingsect-ion 61, said section on one of the units lying over the lip 60 of the next adjacent unit. There is thus made a substantially tions 61 extendingtransversely serving as cleats or ribs to hold the material from running downward by gravity when the conveyer is in operation, it being inclined to the horizontal at such time and the conveyer serving as an elevator for the material thrown thereon. The upwardly pressed ribs 31 on the plate 30 affordspace for the passage of the sides 59 of the material conveying units, as is evident.

A machine made as described may be readily moved to any desired place of useand the end where plates 25 and 30 are attached lowered. This can be done by turning the members 10 to which bars 9 are attached about the axle 1, and further by operating the hand wheel 36 to turn shaft 19. Either one or both of the means for changing the position of the beam or girder on which the conveyer proper is mounted may he used so as to lower the end thereof as much as may be desired. The engine (3 serves to drive the conveyer continuously and dirt shoveled on to the conveyer above the plate 30 is carried in the continuous trough made by the sheetmetal members having bases 58 and sides 59. The dirt will be conveyed upwardly and outwardly and delivered at the upper outer end of the conveyer, the ribs made by the transverse sections 61 carrying the dirtand holding it from running backward down'the conveyer by gravity.

lVith a construction of this character, an ex 'avation may be made under a house or other building substantially as well as in the open. This makes the construction particularly valuable in furnace installation work where a house does not have a cellar or basement to receive the furnace. If the character of the soil permits,'the conveyer chains may be equipped with digging buckets 62. as shown in Fig. 3, which will loosen. and take up the dirt and carry it outward. When thusused, members 63 are attached to the under sides of the beam or girder so as to properly spa e the scoops from the ground. The usual practice. however, will be to loosen and dig the dirt with the usual implements by hand and throw the same on to the conveyer constructed as shown in the other figures of the drawings.

This construction is relatively simple and is very practical andetlective for the purposes for which it is designed. ,The appended claims define the invention and are to be considered. as comprehensive of all forms of structure coming within their scope.
